Description

电子模块的壳体及其制造
技术领域
本发明涉及一种用于电子模块的壳体以及尤其涉及一种用于制造模块的壳体的方法。
背景技术
电力电子领域越来越需要适应特殊应用的电子模块。这种类型的电子模块一般都是小批量生产,这意味着它们的生产比大批量生产电子模块更复杂、更昂贵。这尤其涉及带有特殊端子设备的电子模块的壳体。
用于电子模块的壳体例如通过注射成型来生产,其中,端子被利用塑料注塑包封。这种制造方法的一个优点是端子的“能键合性”,端子在键合过程中不能自然振荡,因此使得键合结果无法控制,并且由于省略了替代的接合工艺来组装壳体,因此不会通过这种类型的接合工艺造成损坏或污染。然而,缺点是对于端子的每种布置都需要专门的注射工具,该模具匹配端子的位置。
在用于制造电子模块的壳体的另一种方法中,以相对较高的速度和力将端子压入事先制造的塑料框架中。以这种方式引入的摩擦选择性地熔化塑料框架并将端子固定地焊接到其位置,或者塑料框架的材料充分屈服并卡住端子。这种方法的一个优点是端子设备的多样性。即使塑料框架已经存在很长时间,端子也能够以不同的方式布置。然而,缺点是在焊盘下方没有材料配合的连接。只有端子将焊盘牢固和限定地压在塑料框架处时,才能够在焊盘上可靠地进行键合。有限制的工艺窗口和所需的高水平的机械协调增加了故障敏感性。此外,并非所有塑料都能够用于此过程,因为例如,高填充塑料往往会破裂而不是选择性地熔化或变形。
在另一种方法中,首先将内框架和外框架制造为单独的塑料注射成型部件。在组装壳体时,首先将所需的端子插入较大的外框架。然后将粘合剂涂在每个焊盘下方,并将所有壳体部件粘合在一起。这种方法的优点是制造过程中的高度稳健性和可变的端子定位。缺点是加工时间长和第二个塑料部件的成本。
发明内容
本发明的目的是提出一种改进的用于制造模块的壳体的方法。
根据本发明,该目的通过具有权利要求1的特征的方法来实现。
本发明的有利设计方案是从属权利要求的主题。
在根据本发明的用于制造模块的壳体的方法中,每个具有能键合的引线表面的引线在注射工具中被利用塑料注塑包封,其中,为每个引线产生管脚凹槽,该管脚凹槽延伸穿过塑料并且包括在引线中的引线凹槽,并且其中,每个能键合的引线表面的至少一部分不被注塑。将导电的管脚元件插入至少一个管脚凹槽中,其中,管脚元件被引导穿过管脚凹槽的引线凹槽。
本发明能够将壳体的管脚凹槽单独地与管脚元件装配,其中,壳体的具有引线和管脚凹槽的壳体框架能够作为系列产品被制造。由此,将壳体框架的批量生产的优点与可适应相应应用的管脚设备相结合。此外,通过在注射工具中注塑包覆引线,能够实现引线的过程技术的可键合性。与将端子压入壳体框架中相比,该方法提供的优点是在制造壳体时不需要特殊的塑料,其防止壳体在端子被压入时破裂。
在本发明的一个设计方案中,每个管脚元件在插入到管脚凹槽中时都与引线形状配合地连接。例如,每个管脚元件都具有收缩部段,其横截面和大小与引线凹槽一致,并且管脚元件的止挡部段分别在在两侧连接至该收缩部段,该止挡部段的横截面大于引线凹槽的横截面。管脚元件与引线的形状配合的连接是这样产生的,即管脚元件的第一止挡部段被挤压穿过引线的引线凹槽,直到管脚元件的第二止挡部段抵靠在引线处。管脚元件与相应的引线的这种类型的形状配合的可连接性有利地实现了壳体的可靠的和可变的管脚装配。为了便于管脚元件插入和穿过引线凹槽,每个管脚元件能够具有一个端部部段,例如锥形的、特别是圆锥形的端部部段,该端部部段以逐渐减小的横截面从第一止挡部段远离地延伸。
在本发明的另一个设计方案中,用于每个待产生的管脚凹槽的注射工具具有冲压部件和凹模部件,二者在注射工具闭合时将管脚凹槽的引线凹槽在彼此相对的侧上封闭,并且在注射工具闭合后利用塑料注塑包封。在此能够提出,在注射工具闭合时,通过将冲压部件压入到引线中来产生或扩大引线凹槽。特别地,每个冲压部件具有被压入引线中以产生或扩大引线凹槽的逐渐变尖的冲压端部。此外,每个凹模部件都具有凹模端部,该凹模端部具有凹部,该凹部由环形壁界定边缘,该环形壁在注射工具闭合之后抵靠在引线上并在一侧处封闭引线凹槽。由此,能够有利地在注射工具的闭合期间产生或最终完成引线凹槽,并且同时在随后的注射成型期间防止塑料浸入。有利地,当冲压部件的冲压端部被压入引线中时,凹模部件的凹模端部中的凹部能够实现引线变形进入到凹部中。
在本发明的另一个设计方案中,每个管脚元件都具有至少一个加厚部段,该加厚部段相对于与其邻接的管脚元件的区域具有扩大的直径,该扩大的直径在引线凹槽外部与管脚凹槽的直径一致。由此,管脚元件有利地稳定在管脚凹槽中。
在本发明的另一设计方案中,每个管脚元件被设计成,使得管脚元件的接触端在插入管脚凹槽之后从管脚凹槽伸出。由此,能够容易地从外部接触管脚元件。
在本发明的另一设计方案中,管脚元件在插入到管脚凹槽中之前布置在印刷电路板处并且同时插入到管脚凹槽中。以这种方式,管脚元件不必单独插入管脚凹槽中并且随后以复杂的方式与印刷电路板连接。此外,能够提出,壳体被制造为具有至少一个固定元件,例如具有螺纹凹槽、卡钩和/或锁定凸起,其设计用于将印刷电路板固定到壳体处。如果印刷电路板能够固定在壳体上,则能够省略上述引脚元件与引线的形状配合的连接,因为引脚元件通过印刷电路板被保持在引脚元件的位置,由此,能够利用引脚设备替换印刷电路板。
在本发明的另一个设计方案中,引线以引线框的形式被制造,其中,引线框具有引线保持部,并且引线保持部在引线的注塑包封之后从引线上被分离或移除。由此,简化了将引线插入到注射工具中。例如,能够制造具有预设断裂位置的引线框,用于将引线保持部与引线分离。由此,有利地简化了引线保持部与引线的分离。
使用根据本发明的方法制造根据本发明的壳体。根据本发明的电子模块具有使用根据本发明的方法制造的壳体。根据本发明的壳体和根据本发明的电子模块的优点对应于根据本发明的方法的上述优点。

图6示出了在注射成型期间在一个位置中的变形的引线9、冲压端部25和凹模端部27,在该位置中,引线凹槽17被冲压端部25和凹模端部27封闭。
图7示出了在注射成型后注射工具20打开期间在一个位置中的变形的引线9、冲压端部25和凹模端部27,其中,冲压部件21和凹模部件23沿着圆柱轴线33在彼此相反的方向上从引线9移开(喷射注塑的塑料未示出)。
在图4至图7所示的实施例中,引线9的引线凹槽17已经在引线框5的制造期间被预制,并且在注射工具20闭合时如所描述的那样被扩大和封闭。在另一个实施例中,首先通过在注塑模具20闭合时将冲压端部25压入引线9中来产生引线凹槽17。在另一实施例中,引线凹槽17在引线框5的制造期间完全被预制,并且仅在注射工具20闭合时分别通过冲压部件21和凹模部件23来封闭。
在喷射注塑之后,管脚元件37被插入管脚凹槽7中,其中,它们各自以形状配合的方式锚定在引线9的引线凹槽17处(见图10和11)。
图8和图9示出了在管脚元件37插入管脚凹槽7之后的壳体1。在此,图8示出了壳体1的一个部段的立体图,并且图9示出了壳体1的截面图。每个管脚元件37具有两个加厚部段39,加厚部段分别具有与管脚元件37的相邻区域相比扩大的直径,该直径与引线凹槽17外部的管脚凹槽7的直径一致。管脚元件37通过加厚部段39稳定在管脚凹槽7中。每个管脚元件37的接触端41在其被插入管脚凹槽7中之后从管脚凹槽7中伸出。
图10和图11以立体图示出了当将管脚元件37插入管脚凹槽17中时的管脚元件37的引线侧端部和引线9,其中,引线9以剖面图示出。管脚元件37的引线侧端部具有收缩部段43,该收缩部段在其横截面和其伸展方面与引线凹槽17一致,并且在两侧连接有止挡部段45、47,止挡部段的横截面大于引线凹槽17的横截面。通过管脚元件37的第一止挡部段45沿力方向35压穿过引线凹槽17直到管脚元件37的第二止挡部段47抵靠在引线9处,使得建立管脚元件37与引线9形状配合的连接。管脚元件37具有锥形端部部段49,该锥形端部部段以逐渐减小的横截面积从第一止动部45远离地延伸,并且简化了将管脚元件37压入到引线凹槽17中。图10示出了管脚元件37在与引线9连接之前的位置。图11示出了与引线9连接之后的管脚元件37。止挡部段45、47用作为倒钩,其防止管脚元件37与引线9的连接松脱。
图12(图12)示出了在将印刷电路板51安装在壳体1的壳体框架19的上侧处之前的具有壳体1和印刷电路板51的电子模块3的实施例的立体图。利用根据图1至图11描述的方法制造壳体1,其中,管脚元件37在被插入到管脚凹槽7(例如通过焊接)之前被布置在印刷电路板51处,并且同时被插入到壳体框架19的管脚凹槽7中。壳体框架19被制造为具有螺纹凹槽53,螺纹凹槽被设计用于将壳体框架19与印刷电路板51拧紧。电子模块3能够具有其他部件(未示出),例如布置在壳体框架19的下侧处的基板和/或布置在壳体框架19下方的散热器。此外,电子模块3具有布置在印刷电路板51、基板和/或散热器上的电子模块,这些同样未示出。
尽管已经通过优选实施例对本发明进行了详细说明和描述,但是本发明不被所公开的示例限制,并且本领域技术人员能够在不脱离本发明的保护范围的情况下从中得出其他变体方案。
